ANALYSIS OF LIGHT WEIGHT SMART AUTHENTICATION PROTOCOL SCHEMES FOR EFFECTIVE COMMUNICATION IN SMART ENVIRONMENT

Smart home IoT networks have been recognized as one of the common and part of daily life in coming 5G era. Internet of Things (IoT) sensors are used in daily routine by the users to control the home services through remote access anywhere anytime. Without being protected, network management can cause smart home networks to be vulnerable to various security threats. It is so important to protect data traffic transmitted between user mobile devices and their in-home IoT appliances because they include users' sensitive and critical privacy information. To overcome this problem a new method is proposed known as Lightweight and Robust mutualauthentication scheme (LRMA) for protecting distributed smart environments from unauthorized abuses. In smart environment between smart devices uses implicit certificates and enables mutual authentication and key agreement. Computation and communication complexities are reduced to obtain efficiency and various attacks are resists to LRMA. Moreover, both security analysis and performance evaluation prove the effectiveness of LRMA as compared to the state of the art schemes
